Comparison of the laryngeal mask airway Supreme and laryngeal mask airway Classic in adults.

Background And Objective: The laryngeal mask airway (LMA) is an important airway device that was developed in 1983. From the first classic LMA models up to now, LMA models have been developed that are easily and quickly inserted, provide ventilation at higher airway pressures, have lower cuff pressure, a reduced risk of gastric aspiration and cause fewer stress responses. We aimed to compare the LMA Classic with the LMA Supreme in assessing the success rate and time for insertion, number of attempts and leak pressure.
